Primary objectives
• To test the hypothesis that a FDC-based strategy (a “polypill”) for delivery of preventive medications (aspirin, statin & 2 BP lowering drugs) compared with usual care might improve:
– Adherence to indicated therapy
– Systolic BP
– LDL-cholesterol,
at the end of the study,
in people with (or at high risk of) CVD.
UMPIRE trial
Patients with established CVD; or at ≥ 15% 5-year risk (n = 2000, India & Europe)
Treatment strategy based on fixed dose combination
Continued “usual care”
Randomisation
24 months or End of Study *
1 month, 6 month, 12 month, 18 month follow-up
PROBE design (c/o IMPACT & Kanyini-GAP)
inclusion exclusion: contraindications or known intolerance of FDC components * 12 months after last randomisation (range 12 – 24)
Methods
• Adherence: self-reported use of [antiplatelet, statin and ≥2 BP lowering drugs]
• BP: electronic Omron 705CP II + printer
• Cholesterol & blood tests: local laboratories
Randomisation
• FDC : usual care, 1 : 1 (web-based)
• Stratified by presence or absence of established CVD
• 28 in India
• 3 in Europe (Dublin, London, Utrecht)
Trial sites
• June 2010 – July 2011
Recruitment
Fixed dose combinations, x 2
Version 1 Version 2
aspirin 75mg
simvastatin 40mg
lisinopril 10mg
atenolol 50mg
aspirin 75mg
simvastatin 40mg
lisinopril 10mg
hydrochlorothiazide 12.5mg
Usual care
As per local clinical guidelines.
Study treatments
Physicians could add additional medications, stop the FDC & begin treatment with separate medications, or switch FDC version.
Participants in the FDC group were dispensed study FDC free of charge from their trial centre. Participants in the usual care group acquired their medications subject to local payments or exemptions; 966 participants (48%) were exempt from medication charges.

Conclusions
• An FDC strategy including aspirin, statin & 2 BP lowering drugs improves adherence, BP & cholesterol in patients with established CVD & those at high risk.
• The effect, a 33% increase in adherence over a median interval of 15 months, was evident in a trial population with an unusually high reported use of indicated medication at the outset.
• The greatest effect, a 3-fold increase in adherence, was seen in those non-adherent at the outset.
• The effect on adherence was similar in those exempt or not exempt from medication charges (post hoc analysis).
